High-spin states in the odd-odd ${}^{174}$Re have been investigated via the ${}^{152}$Sm(${}^{27\phantom{\rule{-0.16em}{0ex}}}$Al, 5$\mathit{\text{n}}\ensuremath{\gamma}$)${}^{174}$Re reaction with the help of excitation function, x-$\ensuremath{\gamma}$, and $\ensuremath{\gamma}\ensuremath{-}\ensuremath{\gamma}$ coincidence measurements. Five rotational bands have been observed and their configurations were assigned based on alignments, band crossing frequencies, electromagnetic properties, and the estimated bandhead excitation energies. Low-spin signature inversion has been identified in the two-quasiparticle bands built on $\ensuremath{\pi}{h}_{11/2}\ensuremath{\bigotimes}\ensuremath{\nu}{i}_{13/2}$, $\ensuremath{\pi}{h}_{9/2}\ensuremath{\bigotimes}\ensuremath{\nu}{i}_{13/2}$, and $\ensuremath{\pi}1/{2}^{\ensuremath{-}}[541]\ensuremath{\bigotimes}\ensuremath{\nu}5/{2}^{\ensuremath{-}}[512]$ configurations. $E2$ interband transitions were analyzed with band-mixing calculations giving information on shapes and shape driving effects for the bands of interest.
